Description

technical field [0001] The invention relates to a high-strength and high-conductivity rare earth copper alloy magnet wire and a preparation process thereof. Background technique [0002] High strength and high electrical conductivity are a pair of contradictory properties, and copper alloy materials are no exception. At present, the basic principle of developing high-strength and high-conductivity copper alloy materials is usually to add alloy elements with low solid solubility to copper, and through high-temperature solution treatment, the alloy elements form a supersaturated solid solution in the copper matrix, which improves the strength and conductivity. After aging treatment, the supersaturated solid solution decomposes, and a large number of alloying elements precipitate out in the copper matrix as precipitated phases, and the electrical conductivity increases rapidly. At the same time, the strength is further improved due to the dispersion strengthening effect of the ...
